Kelly Brook may be going through a break-up but by the looks of things she is far from heartbroken.

The 33-year-old was back to work with a bang in a revealing forties two piece as she shimmered on set of her latest photoshoot in Miami looking sun-kissed and relaxed.

Since news of her split from Thom Evans emerged Kelly has been keeping a low profile, relaxing and sunbathing on a solitary break in Miami.

Ever the professional Kelly posed up in a gorgeous floral two-piece from her own collection, the high-waisted tight shorts perfectly showed off her toned hourglass figure.

Her curves were on show in the busty top with a low-cut sweetheart neckline - a look sure to make ex Thom green with envy.

If Kelly was feeling the strain of the break-up she hid it well as she grinned and posed on the shoot.

Her shoot, which is to advertise her summer collection for New Look, certainly got the attention of onlookers in the Miami sunshine, with Kelly swapping the two-piece for a stylish all-American girl A-line dress.

Former Big Breakfast presenter Kelly showed she is certainly the curvy girl's pin-up as she stunned in the checked dress, which with its wide shoulder straps and deep plunging neckline made the model stop traffic.

Her smile on the shoot was a million miles away from the solitary figure the star cut as she sunbathed alone on her hotel earlier this week.

Either Kelly is an expert at hiding her feelings or the glorious sunshine in Miami has lifted her spirits.

Earlier in the day the pretty brunette looked girly in a floaty, floral dress, clutching a cup of coffee and had her dark hair pinned up ready for the shoot.

Even her casual mullet dress highlighted her gorgeous curves and Kelly couldn't stop smiling as she returned to work.

The star, who's been in Miami for the last few days, announced the split from her boyfriend of two years via her Twitter account on Friday.

But instead of moping around at home, Kelly has been sunning herself in the US, amid rumours that she's reunited with former partner Danny Cipriani.

The model was up bright and early on Sunday and couldn't seem to stop smiling as she headed from her car to the location of her New Look shoot.

As well as modelling some rather thigh-skimming outfits Kelly slipped into some tight blue jeggings, and a navy all-in-one.

Kelly's various outfits certainly showed off her figure, which doesn't seem to have changed post-break up.

Having clearly made an effort for her day of work, Kelly wore a long, floaty dress blue dress which had a feminine, floral pattern.

She wore her trademark dark hair pinned up in small rollers and added a huge pair of sunglasses to cover her make-up free face.

The unlucky-in-love model carried her favourite Chanel shopper over one arm and clutched a takeaway coffee cup in the other, clearly in need of a caffeine fix.
